vm build using --raw and LVM logical volume doesn't boot because of Grub install error

[Simon Huerlimann]

This is with Karmic and vm-builder 0.11.3-0ubuntu1

I've set up a kvm host using an LVM logical volume as --raw device. The vm building didn't show any problems.

But the vm doesn't boot at all. Using VNC I've found out that it halts after 'Booting from Hard Disk...'. Looks like grub hasn't been installed on the correct place.

Mounting the vm root partition in the host, I was able to locate the vmbuilder-install.log

The IMHO interesting snipplets are:

Not sure if hd0 => /dev/sda is a valid idea...

Will try to manually install grub now...

This is fixed in Lucid.
